Perhaps you should try some spelling variations:
"advance computational _ computer program" » "advanced computational _ computer program" (Expand search), "advancing computational _ computer program" (Expand search), "advanced computations _ computer program" (Expand search)
"using computational and example of" » "and computational and example of" (Expand search), "using computational fluid example of" (Expand search), "using computational and examples of" (Expand search), "using computational an example of" (Expand search), "using computational and sample of" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("advance computational _ computer program") OR ("using computational and example of"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advance computational _ computer program\") OR (\"using computational and example of\"))".
• Removing quotes may allow a broader search: (( advance computational _ computer program ) OR ( using computational and example of )).
• Adding a wildcard symbol may retrieve word variants: (("advance computational _ computer program") OR ("using computational and example of"))*.
